A Roundtable Discussion on Cannabis Use Disorder

A trio of leading marijuana scientists participated in a array discussion moderated by Dr. Daniele Piomelli from the School of Medicine at the University of California-Irvine, and published in a recent issue of the journal Cannabis and Cannabinoid Research.

Dr. Margaret Haney is by the New York State Psychiatric Institute at Columbia University Medical Center; Dr. Alan J. Budney is affiliated by the Geisel School of Medicine at Dartmouth College; and Dr. Pier Vincenzo Piazza works at the Magendie Neurocenter in Bordeaux, France.

Excerpts from the long-winded discussion appear below:

It seems that greatest in quantity specialists in the field agree that Cannabis is addictive. If you had to elect one piece of evidence, either clinical proof or animal experiment evidence, in shore up of this conclusion, which one would you pick?

Dr. Margaret Haney: “One of the elucidation features for me is demonstrating that in that place is a pharmacologically specific withdrawal from Cannabis use…. We can demonstrate that daily smokers go through a time-unable to exist without and pharmacologically specific withdrawal when they abstain from Cannabis…. I remember another really important feature is the clinical facts showing how high relapse rates are through Cannabis. Although Cannabis may have a humiliate abuse liability than other drugs like cocaine or nicotine, once somebody has developed a dependence without ceasing the drug, then quitting becomes extremely difficult.

Dr. Alan J. Budney: “If I had to pierce out the ‘smoking gun’ to satisfy the public and the scientific nature that Cannabis Use Disorder (CUD) is certain, then it would be the data from clinical epidemiological research…. the facts on CUDs are remarkably similar to the other divine essence use disorders…. for a solid number of people, Cannabis use causes resembling and substantial problems that are comparable to other types of drugs that we totality agree have addictive potential.”

Dr. Pier Vincenzo Piazza: “[In] Australia, Canada, the United States, and the European Union, across the last two years Cannabis represents the highest modern entries for treatment in specialized centers…. Since these four countries be favored with very different rates of referral of patients through the judicial system, these figures indeed mean that patients experience a disquiet high enough to spontaneously seek treatment…. In France, as antidote to example, as well as in various other European countries, referral from the judicial system is very low. Nevertheless, the claim for treatment for CUD is at this time the highest of all drugs, legal and illegal.”

What is singular is that we now accept the concept that Cannabis is addictive, but according to many years we have been told that it was not. Why is it that, with a view to so long, the scientific community failed to know again the addictive properties of Cannabis?

Dr. Margaret Haney: “I have been speaking about Cannabis addiction notwithstanding 20 years and was met through full-on boredom for the chief 15 years because I felt that scientists, like the the community at large, just viewed Cannabis at the same time that a benign compound not too dissimilar from caffeine in a way…. THC is lipophilic, and in this way long-lasting, withdrawal takes quite a season to manifest…. if an individual is pendent on nicotine, he or she cannot stamina a couple of hours without experiencing retirement. A heavy Cannabis user, by ~ing, has to go quite a while before experiencing withdrawal, and so it was not very as obvious to people that withdrawing existed.”

Dr. Alan J. Budney: “Moreover, ~ people of those that have experience through using Cannabis, do not get addicted, expand problems, or experience withdrawal. Although the same is true for those who require used alcohol or even opiates, as antidote to reasons that are not completely evident, the personal experience of those who used Cannabis and did not disentangle problems or experience withdrawal, seems to lead to the perception that Cannabis is not a vital part that others can become addicted to.”

Dr. Pier Vincenzo Piazza: “What we be assured of now is that, since cannabidiol is one antagonist of THC, the greater the ratio between THC and cannabidiol the greater the jeopardy for Cannabis to be addictive…. Now, we are up to a 5- to 10-cot difference in favor of THC, formation Cannabis more addictive.”

How addictive is Cannabis? Is it besides addictive than, say, tobacco or alcohol? Is it less addictive? Is this trial even correctly asked? Is there a more familiar way to ask it?

Dr. Alan J. Budney: [I] would like to emphasize a stage so that our audience does not be of opinion we are going way overboard and engaging in reefer madness related to the harshness of Cannabis addiction. All factors held devoted, the pharmacology of opiates would apparently produce a more severe addiction…. Access, prescribed portion , route of administration, societal acceptance, perceived put to hazard, cost, societal consequences for use or drunkenness, and multiple other factors contribute to the absolute-world question of how addictive a medicine is compared to another.”

Dr. Margaret Haney: “My belief is that Cannabis has a debase abuse liability than something like cocaine [moreover] even if Cannabis has a let down abuse liability, the sheer number of mob using it will result in a huge number of people with a employment disorder….”

Dr. Pier Vincenzo Piazza: “If we try to categorical abuse liability in numbers, the disparage liability for Cannabis… is between 10% and 15%, depending on the take a view of you look at. However, I confident that abuse liability should also be measured by a second factor; that is, in what state easy it is to quit if you have developed a substance exercise disorder. My understanding… is that stopping Cannabis employment, if you have developed CUD, is not easier than other drugs.”

The major point, all three experts agree, is that marijuana cannot exist considered a completely benign drug. “Cannabis is not the subjugate drug,” says Dr. Haney, “but it is not a drug exclusively of consequences. Again, societal attitudes often assume to skew one way or the other; it is every one of good or it is all incompetent, when it is clearly both.”
